Volcanoes of the World (VOTW) - NW Rota-1 (284211) Citation

When the new website was launched in May 2013 following three years of database conversion and restructuring, this catalog of Holocene volcanoes and eruptions was renamed "Volcanoes of the World" with an initial version of 4.0, in recognition of the three previous editions of the book published by Smithsonian scientists (in 1981, 1994, and 2010) with the same title.

Only a major change to the database structure will trigger a change to the top version number. Second-level updates will be incremented following the completion of updates to a calendar year of current eruptions. The 4.0 version had eruptions updated through 2010, so 4.4.0 was complete (to the best of our knowledge) through 2014. Minor third-level updates will be done for all other reasons, including general updates from work with the professional literature, current eruptions based on Weekly or Bulletin reports, and minor database schema changes.

Improvements to the functionality, content, or appearance of the website are not logged as part of the database versions. Previous versions are not available, so any use of content from the website should include the database version number and download date as shown above.

4.6.1

7 Aug 2017

Current eruptions updated through 30 July 2017. General updates to volcano data, lists, and eruption histories. Volcanoes with known Pleistocene eruptions and current unrest (usually geothermal activity), but no Holocene eruptions, have been removed from the list of Holocene volcanoes. Information about those volcanoes is still available because of the website expansion to show Pleistocene volcanoes in 2016 (see v. 4.4.2 update). The Holocene list is now restricted to those volcanoes thought to have actually erupted in that time period.

4.3.0

3 July 2014

Completed review of 2013 eruptions. Current eruptions updated through June 2014.
The Holocene volcano list now includes those with known Pleistocene eruptions but exhibiting current volcanic unrest; note that the website prior to 2013 included these as well, listed as "Pleistocene with thermal activity." Renamed the categories used to show the evidence (previously called the "Status") for inclusion in the Holocene list: Eruption Observed, Eruption Dated, Undated Evidence, Unrest / Holocene, Uncertain Evidence, Uncertain Observation, and Unrest / Pleistocene. Audited the "Uncertain Observation" category (48 entries), resulting in the removal of 20 entries and changing another 14 to a different category. Audited "Unrest / Pleistocene" category (42 entries). Reviewed all Greater Caucasus volcanoes. Reviewed volcanoes with volcano type of "Hydrothermal field" (15) and reclassified; removed HTF as a morphology type. With those changes, as of this update we list 1,559 volcanoes thought to have erupted or been otherwise volcanically active during the Holocene.
